2021/8/4
Climate conditions play a significant role in the reproductive success of mature female Antarctic krill and are a factor in fluctuations of the population that occur every five to seven years, a new s...
Antarctic Circumpolar Current flows more rapidly in warm phases
ACC warm phases climate change
2021/8/4
Our planet's strongest ocean current, which circulates around Antarctica, plays a major role in determining the transport of heat, salt and nutrients in the ocean. An international research team led b...

Instability Antarctic ice projected worst-case sea level rise
2019/10/23
Images of vanishing Arctic ice are jarring, but the region’s potential contributions to sea level rise are no match for Antarctica’s. Now, a study says that instability hidden in Antarctic ice increas...
